Hardwood Floor Refinishing in Gilroy — FAQ

How long does hardwood refinishing take?+

A typical 500 sq ft room takes 4–5 days including sanding, staining, and 2–3 poly coats with dry time. The room is unusable during this period.

Water-based vs. oil-based polyurethane?+

Water-based dries faster (2–3 hours between coats), has low odor, and dries clear. Oil-based adds a warm amber tone, is more durable, but takes longer to cure and has strong fumes.

Can engineered hardwood be refinished?+

It depends on the veneer thickness. Engineered floors with a 2mm+ wear layer can typically be refinished once. Thicker 4mm+ veneers can handle 2–3 refinishes.

Is dustless sanding really dustless?+

Dustless systems capture 95–99% of sanding dust, but some fine particles escape. We seal doorways and HVAC vents to minimize dust spread throughout the home.
